Hazards Identification EMERGENCY OVERVIEW Vapors irritating to the eyes and respiratory system. Skin contact may cause irritation and dermatitis. Inhalation of vapors may depress the central nervous system causing dizziness, headache and nausea and eventual loss of consciousness and respiratory paralysis at very high concentrations. Flammable. ROUTE OF ENTRY: Skin Contact Skin Absorption No Eye Contact Inhalation Ingestion Revised: 6/7/96 Page 1 of 7
HEALTH EFFECTS: Exposure Limits Teratogen Synergistic Effects None reported Irritant Reproductive Hazard Sensitization No Mutagen Carcinogenicity: -- NTP: No IARC: No OSHA: No EYE EFFECTS: Contact will cause irritation, redness and a burning sensation. Persons with potential exposure to hexane should not wear contact lenses. SKIN EFFECTS: Hexane is an irritant to the skin and can be absorbed through the skin in harmful amounts. INGESTION EFFECTS: Ingestion may cause gastrointestinal irritation, nausea, vomiting and headache. INHALATION EFFECTS: Inhalation of the vapors may depress the central nervous system causing dizziness, difficulty in walking, respiratory tract irritation, numbness of the extremeties and may result in eventual respiratory paralysis at very high concentrations. Some evidence indicates hexane may cause mutagenic, teratogenic, and/or reproductive effects MEDICAL CONDITIONS AGGRAVATED BY EXPOSURE: Any type of paresthesia may be aggravated by hexane exposure. NFPA HAZARD CODES HMIS HAZARD CODES RATINGS SYSTEM Health: 1 Health: 1 0 = No Hazard Flammability: 3 Flammability: 3 1 = Slight Hazard Reactivity: 0 Reactivity: 0 2 = Moderate Hazard 3 = Serious Hazard 4 = Severe Hazard 4. First Aid Measures EYES: Flush contaminated eye(s) with copious quantities of water. Part eyelids with fingers to assure complete flushing. Continue for minimum of 15 minutes. Seek medical attention. SKIN: Flush affected area with large quantities of water. Remove contaminated clothing as rapidly as possible. INGESTION: Do not induce vomiting as aspiration into the lung may cause pulmonary edema and complications. Do not administer milk, alcohol or fatty foods. Lay victim down in a cool, quiet, well ventilated area and keep warm with a blanket. Consult a poison control center for instructions as soon as possible. INHALATION: Revised: 6/7/96 Page 2 of 7
Conscious persons should be assisted to an uncontaminated area and inhale fresh air. Quick removal from the contaminated area is most important. Unconscious persons should be moved to an uncontaminated area and given artificial resuscitation and supplemental oxygen. Further treatment should be symptomatic and supportive. PROMPT MEDICAL ATTENTION IS MANDATORY IN ALL CASES OF OVEREXPOSURE TO HEXANE. Rescue personnel should be equipped with self-contained breathing apparatus and be aware of extreme fire and explosion hazard. 5. Fire Fighting Measures Conditions of Flammability: Liquid and vapor flammable Flash point: Method: -7 o F (-22 o C) Not Available LEL(%): 1.7 UEL(%): 7.7 Hazardous combustion products: Typical for burning hydrocarbon Sensitivity to mechanical shock: None Sensitivity to static discharge Autoignition Temperature FIRE AND EXPLOSION HAZARDS: Vapors may accumulate in areas with inadequate ventilation possibly forming an explosive atmosphere. Use adequate ventilation to prevent vapor buildup. EXTINGUISHING MEDIA: Water (foam), dry chemical, carbon dioxide. FIRE FIGHTING INSTRUCTIONS: If possible, stop flow of hexane. Use water spray to cool surrounding containers. Wear self-contained breathing apparatus and other protective clothing as required to fight fire. 6. Accidental Release Measures Evacuate all personnel from affected area. Use appropriate protective equipment. If leak is in user s equipment, be certain to purge piping with inert gas prior to attempting repairs. If leak is in container or container valve, contact the appropriate emergency telephone number listed in Section 1 or call your closest BOC location. 7. Handling and Storage Electrical Classifications: Class 1, Group not specified. Earth-ground and bond all lines and equipment associated with the hexane system. All electrical equipment should be non-sparking or explosion proof. Revised: 6/7/96 Page 3 of 7
Use only in well-ventilated areas. For gases, valve protection caps must remain in place unless container is secured with valve outlet piped to use point. Do not drag, slide or roll cylinders. Use a suitable hand truck for cylinder movement. Use a pressure reducing regulator when connecting cylinder to lower pressure (<3000 psig) piping or systems. Do not heat cylinder by any means to increase the discharge rate of product from the cylinder. Use a check valve or trap in the discharge line to prevent hazardous back flow into the system. Protect cylinders from physical damage. Store in cool, dry, well-ventilated area away from heavily trafficked areas and emergency exits. Do not allow the temperature where cylinders are stored to exceed 130 o F (54 o C). Cylinders should be stored upright and firmly secured to prevent falling or being knocked over. Full and empty cylinders should be segregated. Use a "first in-first out" inventory system to prevent full cylinders being stored for excessive periods of time. Post "NO SMOKING OR OPEN FLAMES" signs in the storage area or use area. There should be no sources of ignition in the storage or use area. For additional recommendations, consult Compressed Gas Association s Pamphlet P-1. Never carry a compressed gas cylinder or a container of a gas in cryogenic liquid form in an enclosed space such as a car trunk, van or station wagon. A leak can result in a fire, explosion, asphyxiation or a toxic exposure. 8.

IDLH: 5000 ppm LD 50 2870 mg/kg (rat) ENGINEERING CONTROLS: Use a laboratory hood with forced ventilation for handling small quantities. Use local exhaust to prevent exposures above exposure limits. EYE/FACE PROTECTION: Chemical safety goggles or glasses and face shield. Do not wear contact lenses. SKIN PROTECTION: Use nitrile rubber gloves. RESPIRATORY PROTECTION: Positive pressure air line with full-face mask and escape bottle or self-contained breathing apparatus should be available for emergency use. Revised: 6/7/96 Page 4 of 7
